Problems solved by technology
The commonly used ladders are trapezoidal single ladders or ladders with support rods. These ladders lean on the supports or rely on the interaction of the support rods and ladders to bear the weight of the person when they are in use. However, when the user stands relatively high , due to the unstable center of gravity, the ladder is easy to slide, which endangers the life safety of the user
On the other hand, due to the relatively large size of the ladder, it is very inconvenient to move, especially for long-distance movement or transportation; secondly, even when the ladder is not used, the ladder still needs to occupy a large space, resulting in the limited space being occupied by the ladder in vain Finally, the ladder also affects the aesthetics, especially for some people who pursue perfectionism

Description
technical field [0001] The invention belongs to the field of daily necessities, and in particular relates to a safety ladder and an overhaul device, which are used for objects that need to be maintained / installed by ascending a height. Background technique [0002] With the development of industry, agriculture and science and technology, and the continuous improvement of people's living standards, ladders, as a very common climbing tool in daily life or work, provide a great tool for people to climb and trim branches and leaves, install things with a certain height, or overhaul objects at high places. Great convenience. The commonly used ladders are trapezoidal single ladders or ladders with support rods. These ladders lean on the supports or rely on the interaction of the support rods and ladders to bear the weight of the person when they are in use. However, when the user stands relatively high , due to the unstable center of gravity, the ladder is easy to slide, which en...
